Is it bad to train when you're still a little sore?
For example, I'm usually the sorest on the 2nd day after training a muscle group, not the very next day.

So, on day 3 of recovery, is it too early to train again? I'm still usually a little sore but I get impatient.

Thanks for input in advance, hoping I don't get trolled but since I never post here idk what to expect.

don't know what how ur workout is constructed, but most likely that it's fine.

Not following anything strict, just working out at a public gym trying to increase my vertical jump by as much as possible in 6 months, hence the impatience.

then practice your vertical jump 5 days a week

No its not. It depends on the straining of your muscles and your pain level. If you tear a muscle, then it's obvious you shouldn't train.

If you want to increase your vert, practice jumping every day. No need weights bruh.

Mix of both beats one or the other

If he's doing plyos: be careful not to overdo those. 120-150 touches per week goes a long way. Look out for "micro-tears" b/c plyos often seem like they're not killing you but they're really hard on tissue--especially at the joints. Jump programs that use mass #s of squat hops & stuff (like Air Alert) work but they're the worst offenders.

@ Champ: weights are the safest way to go and the results come soon enough. If you're aiming to improve vert, focus on the p chain and get 2-3 leg days in each week. For posterior chain workouts, shoot me a PM.

After working out naturally for so long, you honestly have very little room to improve, ESPECIALLY as AGE is coming and it is NOT avoidable, we downgrade at the same time we are trying to progress....

If you're sore, just workout, your body learns to adapt to whatever you give it, do not be afraid

and what are your goals? cutting?bulking?maintaining?
many factors play into your question...

soreness doesn't necessarily mean your muscles aren't recovered, and as AestheticZOB mentioned your body will adapt to the stresses you place on it

Overtraining is moreover a physiological matter.
